The art here is to make the complex simple. I will reject overly fussy designs, it needs to present a lot of information in a clean, non-overwhelming way. Good use of colour and whitespace is key to these designs. There will be no need for imagery in this design other than placeholders, i.e. band avatar images etc. In the application, all these images will be user-sourced.
I have uploaded the AI and EPS versions of the chosen logo. At the moment it's mono, black on white. You have licence to use this logo in any way you like to support your page layout - reversed onto white, different colour, or the two layouts of the logo. Whatever works for your design. If you need an alternate file type, let me know. At the moment I have no preference for colours or themes other than it needs to be a functional app for the professional music industry, so bear that in mind with your choices, and as mentioned before, the simple layout done well will be the one that wins, I have a gut feel!
Just a note that I'm an experienced User Experience Designer / Web Developer so I'm very vocal about what I like / don't like, but hopefully this will be a bonus for you as a designer as I can speak your language hopefully very effectively in terms of critique / direction. I immediately know what works and doesn't work in an interface, what I lack is your creativity!
My input is your output so I will try and give as much detailed feedback for designs I consider serious contenders as I can.
I have a feeling when I see the winning design for the first time I will just know, as I have before on 99 designs. Good luck everyone! :-)
